Q:B1 refractory material refractory time long?: See the specific use of the environment and maintenance

Q:Building ceiling material fire rating: Divided into four grades, non-flammable, flammable, flammable, flammable...

Q:Indoor to do with the gypsum board or good or good use of fire board board, fire board is made of what material ah how environmental: Do wall, then, gypsum board preferred. Cheap, sex Geng Ji Li Li Dian Dian for the bite force can be good. Do not use wood, moisture easily deformed! Fire board is now called the law is not uniform, there are metal panels inside the folder perlite. There is also a layer of wood on the surface of a fireproof material. As well as take carpentry in the fire liquid soak! The Do not know how the decoration company told you! The

Q:Construction of the building when the need to set up a firewall, the most common way is to use solid brick, then do not have this, out of indignation when the fissure when the river with what other can replace, which is better? More: There are a lot of fireproof materials, but the price is generally higher than ordinary bricks, if you use other fireproof materials can certainly replace, but your cost will increase, so for investors is not worthwhile.

Q:Which industry people, to help return to the final decision to do with the tax treasure Japonica ah, refractory materials and fireproof materials like it? I intend to do an industry website, do not know whether the refractory material and fireproof material more conflict: Refractory material is to achieve a certain time and temperature after the material itself flammable, but can not afford to fire is not combustion. (Such as: paper gypsum board) waterproof material is to reach A-class fire-resistant material, the material itself is not burning. Often decisive cut juice with tax treasure japonica (such as: steel fire categories)

Q:How to brush fire paint: 1, before the construction must be on the base (coated material) to clean up, remove the ash, oil and paint to be debris. Wood base should reach the natural dry state, water content <10%. 2, stir even after brushing to ensure the construction quality and product performance. 3, should be above 5 ℃, within 24 hours after construction to avoid rain. 4, the coating is generally coated with two layers, if necessary, can be coated with three layers, or cover the light again, Tu finished the first time, the natural dry after the next layer of construction. Every time the brushing surface shall not be leaked. Per square meter with the amount of ≥ 500g, to a fire safety standards. 5, brushing process using brush, spray or roller, brushing evenly. Brush the direction to be consistent, do not cross or repeatedly brushing. Note winter construction should be above 5 ℃, summer should be below 35 ℃, to avoid freezing or overheating.

Q:Why do the cabinets in the bathroom use fireproof board material, the bathroom is easy to fire?: Plates are multi-purpose, as long as suitable, can be used in different locations.

Q:Production of fire paint business should have what qualifications: Production of fire retardant coating enterprises should have the requirements of ordinary production enterprises qualified business license, organization code, tax registration certificate, system certificate, type approval certificate, public security fire for the record. Fire retardant coating is used for combustible substrate surface, can reduce the surface of the coating material flammability, blocking the rapid spread of fire, used to improve the refractory limit of the coating material of a special coating. Applied to the surface of the combustible substrate, to change the surface of the material combustion characteristics, blocking the rapid spread of fire; or applied to the building components, to improve the fire resistance of the components of the special coating, called fire retardant coating. Fire retardant coating is by brushing the surface of those flammable materials, can improve the material's fire resistance, slow the spread of flame propagation speed, or in a certain period of time to prevent burning, this type of coating known as fire retardant coating, or called flame retardant coating.

Q:Fire-resistant coatings are generally water-based or oily: Common fire-resistant coatings on the market are also water-soluble (oily). Fire retardant coating from the dispersion medium can be divided into: water and solvent-based two. Water-based fire retardant coating: water as a dispersion medium, the emulsion for the film-forming material, in a variety of flame retardants, filler composition of water-based fire retardant coating. Solvent (oil) fire retardant coating: organic solvent for the thinner, resin for the film-forming material, in a variety of flame retardants, fill the composition of solvent-based fire retardant coating. The difference between the two: water-based fire retardant paint green, environmentally friendly fire-resistant coating, is the national and industry recommended species. Solvent-based fire retardant coating because of the organic film in the process of drying, benzene, xylene and other needs to be volatile, so people and the environment have a certain impact, but in a certain environment, solvent-based fire retardant coating fire resistance, water resistance Chemical resistance is water-based fire retardant coating can not reach. With the continuous progress of technology, the future may be completely eliminated solvent-based fire retardant coating.

Q:Phenolic insulation board is B1 grade fireproof material: Bare board is b1 level, complex and after a class
